As you might be aware, the national level Brisbane based Australian UFO Research Network (AUFORN): http://auforn.com/ spent some time in the early 2000's trying to stimulate interest in the idea of an Australian Disclosure project. This did not get far until, the Adelaide based Australian UFO Research Association (AURA), facilitated by Keith Basterfield, committed itself to the concept and the Disclosure Australia project ran from 2003 to 2008. The extensive results of the AURA led project may be seen in detail at: http://disclosureaustralia.freewebpages.org/
These results include a final report, and a listing of all the Australian Government UFO related files which were found by AURA.
Although AURA handed back the project to AUFORN in 2008, having completed its work, AUFORN seem to have done nothing more with the concept since then, apart from copy files from the: http://disclosureaustralia.freewebpages.org website to their own wesbite.
